Abstract
A proton therapy system based on a compact superconducting cyclotron, including: a superconducting cyclotron system, an energy selection system, a beam transport system, a fixed therapy room subsystem and a rotating frame therapy subsystem; a fixed-energy proton beam extracted from a superconducting cyclotron of the superconducting cyclotron system is adjusted into a continuous and adjustable proton beam of 70 MeV to 200 MeV by the energy selection system, thus realizing a longitudinal adjustment for a proton range during treating a tumor, and the continuous and adjustable proton beam is respectively transmitted to the fixed therapy room subsystem and the rotating frame therapy subsystem by the beam transport system. The cooperative control of the superconducting cyclotron system, the energy selection system, the beam transport system and the therapy head realizes the transverse expansion of proton beams, thus realizing intensity modulated radiation therapy for the tumor.
